Remuxing m3u8 to mkv, Can't write packet with unknown timestamp

[ponpon]

Thank you for the excellent command.

I have a issue in remuxing m3u8 to mkv.
I tried

ffmpeg -y -i "https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8" -c copy test.mkv
ffmpeg -y -i "https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8" -c copy -fflags +genpts test.mkv
ffmpeg -y -i "https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8" -c copy -copyts test.mkv
ffmpeg -y -i "https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8" -c copy -copytb 1 test.mkv
ffmpeg -y -i "https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8" -c copy -vsync cfr -r 24 test.mkv
ffmpeg -y -i "https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8" -c copy -vsync cfr -r 24 -fflags +genpts test.mkv
ffmpeg -fflags +genpts -y -i "https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8" -c copy test.mkv

ffmpeg -y -i "https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8" -c copy test.mkv
